Saints coach Sean Payton is no longer merely suspended - at the end of the season, he'll be a free agent.

NFL sources told ESPN's Adam Schefter that, sometime within the past year, the multiyear contract extension the Saints announced for Sean Payton in September 2011 was voided by the NFL, making the suspended head coach a free agent after this season and casting questions on how long he will remain in New Orleans.

Payton is expected to become the NFL's most sought-after head coach after this season, and there already is speculation in league circles that he could wind up returning to Dallas, where he worked as the assistant head coach from 2003 to 2005.
